Hello,
I have a proprietary transport/messaging layer that sits below an MTL
component. This transport layer requires OpenMPI to assign it a rank that
is unique and specific to that process and will not change from execution
to termination. In a way, I am trying to find a one-one correspondence
between a process's universal rank in OpenMPI and this transport layer. I
began looking at ompi_proc_t from different processes and seemingly found
a unique identifier, proc_name.vpid. Consequently, I assigned the ranks to
each process in my transport layer based on the value of the local vpid of
each process.
I have not tested this thoroughly, but it has been working so far.
Although, I would like to make sure that this is a good approach, or know,
at least, whether if there are other ways to do this. I would appreciate
it if you could leave me feedback or give suggestions on how to assign
universal ranks to a proprietary transport software.
Thanks for your help,
Sajjad Tabib
